Product Description
![](https://cdn.z1motorsports.com/imageGallery/d/152638-1/Red_Line_Logo_Z1_Motorsports.jpg)
Red Line Gear Oils and Transmission Lubricants are designed to provide excellent low-temperature shiftability and improved gear protection at higher temperatures. Red Line Gear Oils will reduce differential temperatures 10-70F. Efficiency improvements between 1-5% are typical.
The synthetic base stocks used have tremendous thermal stability and provide the best film strength available. The unique combination of base stocks and additives allow Red Line gear and transmission oils to carry higher loads compared to petroleum lubricants. The stability of these products allow them to be used for extended periods.
Red Line MT-90 is a GL-4 gear oil, safe for brass synchros as it lacks the reactive sulfurs found in most GL-5 oils that cause damage. This is the oil of choice for 300ZX, 350Z, 370Z, G35, G37, and other Nissan manual transmissions.
- 75W90 GL-4 gear oil (similar to SAE 5W40/10W40 engine oil viscosity)
- Popular in Nissan, Mazda, Mitsubishi, VW/Audi, Lotus Elise/Exige, Toyota, Mendeola transmissions and Atlas transfer cases for Off Road
- Offers quicker shifts, perfect synchronizer coefficient of friction
- Safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage
- High performance gear protection and longer synchro life
- Eliminates notchy shifting, even when cold
- Satisfies the gear oil viscosity requirements of 75W90, 80W90, 90 and motor oil viscosities of SAE 40, 10W40 and 15W40
- Recommended for GL-1, GL-3 and GL-4 applications, as well as where most special synchromesh fluids are specified

If you have the dreaded 3rd gear synchro grind in an early 350Z, try this before changing out your transmission. It worked for me. You will see the results after about 200 miles of driving. Saved me thousands$$$.
